Re: [GENERAL] Column Statistics - How to dertermine for whole database

2008-03-12 Thread Adam Rich 
 Is there a query to pg_catalog tables to find out which table/column
 has
 the stat level not at default in 1 sweep?

Try this:

select c.relname, a.attname, attstattarget
from pg_catalog.pg_attribute a, pg_catalog.pg_class c,
pg_catalog.pg_namespace n
where a.attrelid = c.oid and c.relnamespace=n.oid
and n.nspname = 'public' and a.attnum  0

The value -1 means to use the default (set in postgreql.conf)

Funny, that does not work.

note : I did change the nspace value to reflect the DB I'm
using/querying

I've even changed the stat level to 200 (default is 100 or -1)

The nspname setting setting is for schema, not db name.

select c.relname, a.attname, attstattarget
from pg_catalog.pg_attribute a, pg_catalog.pg_class c,
pg_catalog.pg_namespace n
where a.attrelid = c.oid and c.relnamespace=n.oid
and n.nspname = 'xmms' and a.attnum  0 and attstattarget  -1;

This works now. 
The clarification on it being the schema name was useful.
Thanks.
